Can the Pro9000 Mark II do blue?

[tony22]

Do not color manage: very important. It should NOT be changed !!!

Let me just add that these color targets never have an assigned color space - they are just a series of raw color numbers to send to the printer. You may have your default Photoshop color management set to automatically convert all images to your working color space and to not ask before making the change

Not me. I have it set up to always ask if the file is not already in Adobe RGB.

Pharmacist,

I was not disagreeing with the concept of editing the test charts or the need to do this, and I agree with your statement that these charts should NOT be color managed. I was only making the comment that Photoshop may add a color space to the resulting image without your knowledge, depending on how you have configured your defaults in Photoshop. Sorry for any confusion that I may have caused.

Tony22,

Great - that's how I am set up also. One of the difficulties in having a technical discussion like this is that there are always many details that we all take for granted - like how we set the defaults in our software when it was installed 2 years ago. I just wanted to make sure that this wasn't one of those "default details" that affected your results.

If you still aren't satisfied with the profile that you get after the color shift, I'd be glad to run one on my Eye-One Photo package to compare the two profiling software packages. PM me if you are interested so that I can Email the test charts to you (918 patches on 2 sheets).

Well, I profiled again using a preshifted Blue. No difference. I'd repost the comparison but it would be within one or two RGB points identical to what I posted before. I am positive I read the preshifted targets. I could even tell visually they were the preshifted targets. Why S3P produced a profile that got me the same result is odd.

Yes, I did select the right profile in Photoshop.

 

[pharmacist]

Very strange: I get very good result with preshifting the profile. Did you use the perceptual content for printing, because this is important for out-of-gamut colours ?

 

[tony22]

D'oh! Relative Colorimetric was still selected from my last experiment. I'll set it back to Perceptual (which is how I normally do it).

 

[pharmacist]

And is your problem solved now ?

 

[tony22]

Um, no not really. I reprinted with Perceptual and at least to my eyes it looked almost the same. However I am letting it dry for 24 hours before making a final judgement.
